feat: Design tweaks to Skill Manifest Generation Wizard

[tdurnford]

Description

• Endpoints Step
  • Hide the protocol property since it can only be set to 'BotFrameworkv3' at the moment
    • There was a bug in the Adaptive Form package that didn't set the default/const for hidden properties. To resolve this, we shifted the responsibility for hiding fields from the ObjectField to the SchemaField where the default/const values are set.
• Dialog Selection Step
  • Added a description column with an editable field to change the dialog description
  • Added a 'Select all' checkbox and hid the select all checkbox in the table
• Select Trigger Step
  • Added a 'Select all' checkbox and hid the select all checkbox in the table

why was this needed?

Some of the refs in the Dialog Schema refer to 'http://json-schema.org/draft-07/schema#', so it throws the function throws an error since 'http://json-schema.org/draft-07/schema#' is not included in the definitions.
